Notes. Solutions and their uncertainties were obtained by fitting the TOAs using TEMPO2. Glitch numbers follow the counting of RXTE glitches (Antonopoulou et al. 2018); to recover the NICER count, subtract 45. The dagger symbol (†) indicates that $\ddot{ν}$ $\ddot\nu$ was fixed at that value. The numbers in parenthesis are the uncertainties in the last digit.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
